IPC: F02P17/00
Filed: 1989-05-12
Abstract: PURPOSE:To have easy inspection of chip crack, etc., of a transistor by inserting a diode having a certain withstand voltage characteristic in a circuit which triggers a tachometer signal output circuit, and hindering current from flowing through trigger circuit. CONSTITUTION:When a transistor control circuit 4 is driven by an engine control unit 5, current is fed to the primary coil 1a of an ignition oil with turning-on of a transistor 2, and also a high voltage is induced in the secondary coil 1b with turning-off, so that spark discharge is generated in the gap 3 of each ignition plug. At the same time, a tachometer signal output circuit 7 is driven with the voltage divided by resistances 6a, 6b used as a trigger signal, and a tachometer signal is given to a tachometer 8. In this constitution a diode 12 having a specific withstand voltage characteristic is inserted in the abovementioned trigger signal output circuit, and thereby this circuit is hindered from current flow.

Title: Dielectric barrier discharge lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J65/00
Filed: 1993-04-23
Abstract: PURPOSE:To provide an excellent lifetime characteristic and enhance light emitting efficiency by setting an area of one mesh of a conductive net of a dielectric barrier discharging lamp to 6-900mm<2>. CONSTITUTION:In the case where an area (aXb) of one mesh of a conductive net 4 is 6mm<2> or less, it is relatively small so that a micro plasma is generated right near the center of the mesh although being some what unstable. However, a ratio of light absorbed by a conductive element wire becomes large, thus preventing improvement of efficiency. In the case of (aXb) in excess of 900mm<2>, an electric charge charged in the region of a dielectric surface in the center of the mesh becomes more difficult to be discharged through the dielectric surface in contact with the conductive element wire surrounding the mesh because of the large area of the mesh. Consequently, a micro plasma is hardly generated right near the center of the mesh. As a result, (aXb) is set to 6-900mm<2>.

IPC: B01J23/00
Filed: 1983-06-30
Abstract: PURPOSE:To reduce the load of azeotropic distillation and improve the efficiency, in the continuous vapor-phase production of vinyl acetate from ethylene, oxygen and acetic acid, by using a specific amount of acetic anhydride in place of the whole or a part of the continuously supplied acetic acid. CONSTITUTION:In the continuous production of vinyl acetate by the vapor-phase reaction of ethylene, acetylene and oxygen in the presence of a VIII-group metal catalyst (e.g. Pd) under normal pressure-20atm at 50-200 deg.C, acetic anhydride is supplied to the system in an amount to satisfy the formula x<=0.138y+6.59z [x is feeding rate of acetic anhydride (pt.wt./hr); y is feeding rate of acetic acid (pt.wt./hr); z is feeding rate of water (pt.wt./hr)]. Since the water produced by the reaction and the water contained in the supplied raw material are consumed by the hydrolysis of acetic anhydride, the distillation load can be reduced without leaving acetic anhydride in the reaction system nor inhibiting the production of vinyl acetate.

That is, a duty ratio is read out from a map in a memory in accordance with the basic fuel injection, and an ON-OFF valve 9 is controlled in accordance with the duty ratio by means of a fuel pressure control circuit 21. After an injection time period, as a fixed time period, is set to an injection timing control circuit 19, the value which is obtained by subtracting this fixed time from a required time for intake-air stroke, is set as the injection initiating timing. When this injection initiating timing is detected, fuel injection is made from injectors 5.

IPC: F01L1/34
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To enhance the control responsiveness of a valve timing by restricting the reversing phenomenon caused by a varying torque of a cam shaft during rotation of vanes. SOLUTION: This valve timing control device comprises a timing sprocket 1 and a cam shaft and vanes 3 are rotated in the regular and reverse directions to shift the relative rotational phase by supplying and exhausting the oil pressure selectively to the advance side oil pressure chamber 32 and delay side oil pressure chamber 33 formed in a housing 6 so that the opening/closing timing of a suction valve is made variable. A restricting mechanism 10 restricts reverse rotation in the vane rotation from the delay side to advance side with a positive varying torque of the cam shaft.
